以微型燃气轮机组为基础的微电网动态特性

Dynamic performances of a micro-grid based on micro turbine units

随着微电网技术的发展,以微型燃气轮机组为核心的分布式供能系统的重要性日益显现。介绍以国家863计划分布式供能课题为载体基于微型燃气轮机组的微电网的示范工程系统结构以及Capstone C200型燃气轮机组的控制原理。通过一系列的启停、变负荷及甩负荷模式试验,分析以微型燃气轮机组为核心的微电网系统在接入配网后对于电网和对于微电网内负荷的影响情况。研究结果为进一步了解微型燃气轮机组的输出功率特性、微电网的保护设置以及做好微电网的模型仿真等提供了数据支持。

Distributed generation based on micro turbine units plays a more and more important role with the rapid development of micro-grid technologies. In the related national 863 goal-oriented project, the dynamic performances of a micro-grid based on capstone C200 micro turbines were investigated. The structure of the micro-grid and general control principle of the turbine units were studied first. After that, several tests including start, stop, load swing and mode transition were conducted to study the dynamic responses of the voltage and frequency of the micro grid in both grid connecting and standing alone modes. The test results can be used to evaluate dynamic behaviors of m icro-grids and validate models for simulation studies further.
